The major historical studies that have examined American
biology have emphasized the development of experimental biology at
the end of the nineteenth century. In this characterization, the
descriptive branch of biology has often been treated as less than
important and, in several cases, as a hindrance in the application
of...
Deterministic source signature deconvolution is applied to the
processing of marine wide angle and vertical profiler data with air-gun
sources. Optimum results are obtained with a source signature
measured by stacking the signal reflected from a relatively homogeneous
abyssal plain sedimentary environment. This eliminates the need for
the unstable inverse...
The Johnson Creek Basin, Oregon
is an example of the physical and jurisdictional
problems often associated with watershed
urbanization. Implementation of solutions
to problems of water quality and
quantity in the basin have been hindered
by political and social constraints. Reasons
for the failure of previous management proposals
are analyzed...
The Middle Fork John Day River is composed of low gradient, alluvial valley
segments separated by constrained, canyon-like reaches, and has a history of multiple
land-uses. These factors can alter the physical and biological structure of streams, and
disrupt the longitudinal river continuum. I examined habitat, fish, macroinvertebrates,
and primary...
Five Ultra light Fabric Reflux Tubes (UFRTs) were tested in a thermal vacuum chamber at the National Aeronautics and Space Administration's Johnson Space Center in September 1994. These test articles were design and fabricated by staff at the Pacific Northwest Laboratory, operated by Battelle Memorial Institute for the United States...
There were two viable theories of generation, preformation
and epigenesis, existing in the Seventeenth and
Eighteenth Centuries. Due to their irreconcilable nature,
they were often at loggerheads during this time interval.
The status of these generation theories can be effectively
understood in terms of Thomas Kuhn's conception of preparadigm
science....
Otoferlin is a C2-domain, transmembrane protein whose mutated form is responsible for the DFNB9 subtype of prelingual hearing impairment. Mutations in otoferlin cause an autosomal recessive, non-syndromic form of deafness that is characterized by auditory neuropathy/ auditory dissynchrony (AN/AD), meaning that the outer hair cells (OHCs) are normal, and the...
The proposed action is to thin understory trees from around ponderosa pine, sugar pine, white pine, and
Douglas fir in the outer portion of Riparian Reserves in the Jenny Creek watershed. The overall objective
is to maintain and restore the diversity of forest stands near streams in a way that...
In 1968, Congress passed the Wild and Scenic River Act
creating a system of rivers protected from dams and other
development. By 1987, segments of four Oregon rivers were
protected by the Wild and Scenic River System: the Rogue,
Illinois, Owyhee, and a portion of the Snake along the
Idaho...
